Abstract (en)
[origin: US2005142424A1] A fuel cell includes electrolyte electrode assemblies and a pair of separators sandwiching the electrolyte electrode assemblies. Each of the separators includes a plurality of circular disks. First protrusions and second protrusions are provided on both surfaces of the circular disk. The first protrusions contact an anode of the electrolyte electrode assembly, and the second protrusions contact a cathode of the electrolyte electrode assembly. The area of the separators is divided into portions corresponding to the respective electrolyte electrode assemblies. Each of the divided portions of the separators forms a fuel gas flow field and an oxygen-containing gas flow field by sandwiching the electrolyte electrode assembly.
